1. A method for adapting a video stream using a quality of experience (QoE) report, comprising:
- receiving, at a node in a radio access network (RAN), a QoE report with at least one QoE metric from a wireless device;
extracting the at least one QoE metric in a function layer from a QoE reporting layer, wherein the function layer is a layer other than the QoE reporting layer; and
modifying a layer function in the function layer to improve the QoE metric.

Abstract
Technology for adapting a video stream using a quality of experience (QoE) report is disclosed. One method can include a QoE-aware system in a node of a radio access network (RAN) receiving a QoE report with at least one QoE metric from a wireless device. The QoE-aware system can extract the at least one QoE metric in a function layer from a QoE reporting layer. The function layer can be a layer other than the QoE reporting layer. The QoE-aware system can modify a layer function in the function layer to improve the QoE metric.
